I don't use oracle, so I can't do any testing, but the first sign of trouble noted in the log file (lines 192-196) is:

Oracle.h:37:17: error: oci.h: No such file or directory Oracle.h:38:22: error: oratypes.h: No such file or directory Oracle.h:39:20: error: ocidfn.h: No such file or directory Oracle.h:40:18: error: orid.h: No such file or directory Oracle.h:41:17: error: ori.h: No such file or directory

It would appear that those header files are missing or not in a location where the installer can find them. The rest of the errors may be related to these missing header files.

Prior to that there are several comments that say if there are any install problems, you should read the README and README.help.txt files. Have you done that and was there any clues in there that reference the missing header files issue?
